180 New London Overground Carriages

Florence Eshalomi: On 30 December 2018 the Rail Delivery Group announced that London Overground would introduce 180 new carriages on routes in the north of London in 2019. Can you update me on how this introduction is progressing?

The Mayor: London Overground does not recognise the 180 figure quoted. To date, they have taken ownership of 15 new walk-through Class 710 trains. These are in daily use on the Gospel Oak to Barking route and the Watford Junction to Euston route.
The deployment of the remaining 39 trains was scheduled to begin on the services into Liverpool Street by the end of 2019. Unfortunately, these trains have been delayed as Bombardier is working to resolve software issues. London Overground maintains daily contact with Bombardier about this and is doing everything it can to ensure the new 710 stock are in operational service as soon as possible.
In total London Overground is deploying 54 Class 710 trains, the equivalent of 222 carriages.

Data from TfL Noise Readings

Jennette Arnold: Please provide details of the noise data readings taken from residents’ homes following complaints about tube noise between Highbury and Islington and King’s Cross Stations between 2015 and the present day. Please provide a year-by-year breakdown.

The Mayor: The table below sets out the minimum, maximum and average decibel levels from residents’ homes between Highbury and Islington and King’s Cross stations, for each year since 2015. These figures are accurate to the nearest decibel.

Following rail grinding works carried out in this area in September 2019, Transport for London has taken noise measurements at a number of local properties, which have indicated that noise levels have significantly reduced at these properties.
Further readings at these properties will be carried out in January 2020.

Jubilee Line

Caroline Pidgeon: Please publish a table, showing for each separate day of October, November and December 2019the actual frequency of trains operating on the Jubilee Line during peak hours.

The Mayor: The Jubilee line is timetabled to deliver 30 trains per hour through central London stations during the weekday morning and evening peaks.
The attached appendix provides the weekday frequency of trains through central London from October to December 2019.
On 17 October 2019, during Transport for London’s (TfL’s) regular and rigorous safety inspections, a fault was identified on some Jubilee line trains, which has subsequently impacted service levels on the line.
TfL put in place a dedicated team to oversee the repairs and is providing updates to customers and stakeholders on a regular basis. This is a complex piece of work, which involves the manufacture of individual parts and engaging highly specialised engineers to develop fixes. Safety is always TfL’s first priority and all trains have strict safety checks before they are returned to service.
The majority of trains have now returned to service, and TfL is now operating a normal service on the Jubilee line.

Fully Electric Bus Routes

Joanne McCartney: I greatly welcome the introduction of fully electric buses on routes 43 and 134. What further routes are planned to become fully electric and when?

The Mayor: Next year, Transport for London (TfL) expects an additional 100 electric buses to join the bus fleet on a number of single and double-deck routes. TfL expects to announce which routes will benefit from these buses later this year.
